A power system specifically designed to provide reliable electrical power to a telecommunication facility is disclosed. The system includes a number of microturbine generators adapted to provide AC power that is then rectified to DC power by an array of rectifiers. The system is configured so that the microturbine generators are fueled initially by utility-supplied natural gas. In the event the utility-supplied natural gas fails, the system provides propane from a storage tank to fuel the microturbine generators. If both microturbine generator fuel sources fail or their fuel supply becomes exhausted, power is supplied to the rectifiers by a commercial electrical utility. The system also includes a number of hydrogen-powered proton exchange membranes that are operable to supply DC power directly to the facility if both the microturbine generators and the electrical utility fail. Finally, a number of super capacitors are coupled to the bus line directly connected to the facility in order to maintain power if it becomes necessary to switch power sources.
